(Cl. -l il l d) The .present invention relates generally to harvesters, and more particularly to harvesters of the type having a body containing crop treating mechanism such as threshing [and separating. apparatus and a platform pivotally con nected to the body, on which platform is disposed a flexible endless conveyor trainediover a roller, which is journaled on the axis of pivotal movement of the platform relative .to thebody.

The principal object of this invention relatesto the provision of novel and improved means for pivotally supporting the harvester platform onthe body of the implementand which provides for journaling the conveyor roller on the axis of pivotal movement of the platform. A l

more specific object relates to the provision of a novel mounting for the platform and roller which permits removing 7 the conveyor roller without dismounting the. harvester platform from its pivot support on the body. This application is a division of an application, Serial No.

348,128,.filed July 29, 1940, by Anderson, Arnold and Paradise.

The member is retained on the shaft 50 by means of a plate 54, which is supported on the bolts 3| and is apertured to receive the hub member, and clamps over the outside ofthe flange 53, the latter being eccentric in shape to prevent rotation of the hub member relative to the plate 54. Excess axial movement of the roller shaft 50 relative to the hub member 5| is prevented by a shoulder 55 on the end of the roller I4, which bears against the inner end of the hub member 5|, and by a plurality of shims or washers 56, which bear against the outer end of the hub 5i and are secured to the end of the shaft 50 by means of a bolt 51, threaded into a tapped opening in the end of the shaft 50.

The opposite end of the roller [4 is supported on a trunnion shaft 58, which is carried in a hub member 60 by means of a roller bearing 6|. The exterior surface 59 of the hub member 60 is cylindrical and is slidable into the central 1 opening 62 of the annular bearing member 40,

and is held therein against rotation and also against axial movement with respect thereto by means of a lubricating fitting 63. The fitting B3 is inserted through an aperture 64 in the annular bearing member 40 and is threaded into a suitable aperture in the hub member 60. Since both the aperture 62 in the bearing member 40,

as well as the aperture 24 in the platform supporting flange 23, are made larger in diameter than the diameter of the roller [4, the latter may be withdrawn through the openings 24, 62

without disturbing the pivotal support of the platform,

The roller M can be removed from its mounting [by simply removing the bolt 51 in the outer end of the shaft 50 and also the lubricating fitting 63, after which the roller M can be withdrawn laterally from the side of the platform.

The platform conveyor is driven through a I V-belt pulley 65, which is fixed on a flange 66 of a hub 61 by bolts 68. The hub 61 is tightly mounted on the tapered portion 69 of the trunnion shaft 58.
